Will the work close my venue?

No. The entire application is carried out from the outside. Your venue keeps welcoming the public, and the work is organized around your operating hours.

What's the gain for my guests' comfort?

By dropping the temperature under the roof, the coating makes the space more pleasant in summer, so guests stay longer and leave happier.

Does the coating cut my air conditioning bill?

Yes. With less heat coming through the roof, your cooling units work less, especially in large open spaces.

Does it work if my venue isn't air-conditioned?

Yes. The benefit is then measured in comfort: the roof transmits less heat and the environment stays more bearable.

The effect is minimal. The winter sun is low and rarely out. The slight off-season loss is largely offset by the summer gain.

Why act now

An overheated venue, means guests who don't stay.

Hotel, restaurant, gym or event hall: heat degrades the experience, keeps the air conditioning running and hurts your image.

Guests cut their visit short

Uncomfortable guests stay for less time and are less likely to return.

Air conditioning works overtime

When the roof heats up, the cooling units run nonstop and the bill climbs.

Your image suffers

A venue that's stifling in summer degrades the experience and your online reviews.

Guest comfort at stake

Welcoming the public calls for special attention to comfort and safety during hot weather.

The Covalba solution

Your roof reflects the sun instead of absorbing it.

Covalba makes a reflective roof coating that bounces back up to 90% of the sun. Applied by your roofing contractor, it keeps the roof from heating up: the air inside drops by 8 to 10°C and your air conditioning works less hard.

Conventional roof — up to 80°C at the surface

Dark surface
Absorbs heat
Strains air conditioning

Reflective roof — up to 90% of radiation reflected

Light-colored surface
Stays cooler
Reduces the thermal load

Durability

The Covalba system lasts longer on your roof.

On the roof of a public venue, performance has to last: comfort, image and energy bills can't depend on a coating that wears out in two seasons.

Tout comprendre sur le sujet.

Reflective roof coating for public venues: guest comfort and air conditioning.

Public venues all share one thing: the guest experience drives the business, especially during heatwaves.

Why a venue overheats in summer

A large dark roof can hit 80°C at the surface and drive that heat down into the spaces the public uses.

Guest comfort and business

A venue that’s too hot sees guests cut their visits short. A reflective roof keeps the space pleasant through a heatwave.

The right coating by venue type

Hotels, restaurants, cinemas, gyms and places of worship all gain from a lighter heat load without heavy works.

Keeping the air conditioning bill down

With less heat coming through the roof, a reflective coating takes the strain off cooling equipment in large open spaces.

Protection that lasts

Covalba polyurethane systems with a finishing varnish are designed to last 8 to 10 years while protecting the waterproofing.
